Many algorithms that require a sequence only need __len__ and __getitem__. The
term sequence is used to distinguish such containers from mere iterables that
only provide __iter__ (and may be consumed by iteration). The glossary entry
covers this use of the

As Amaury notes, implicit ducktyping is not feasible for sequences or mappings,
as the method names overlap - you have to add explicit semantic information to
say which kind of container you're implementing.

Thanks, Nick.
I see that the sequence doesn't have strict definition.
Though, I think collections.abc module's document should describe
this manner. For example:
But checking type with these abc may be too strict for most case.
For example, some user defined

So, I feel the 2nd meaning of sequence should be

sequence types in stdlib have richer API then the ABC. (e.g. comparison, +,

They are APIs that sequence may have but not APIs makes the type sequence.
